Application Of Abdominal Drainage Tube In The Operation Of Gastrointestinal Malignancies In Elderly Patients Under The Concept Of Enhanced Recovery After Surgery

Objective:To investigate the effect of avoiding indentured abdominal drainage tube on postoperative rehabilitation of elderly patients with gastrointestinal tumors under the concept of enhanced recovery after surgery.Methods:A total of 96 elderly patients with gastrointestinal malignancies were included and randomly divided into ERAS group and abdominal drainage group.In ERAS group,abdominal drainage tube was not routinely indentured during operation,while in the abdominal drainage group,1-2 abdominal drainage tubes were routinely indentured during operation.The general data,postoperative recovery,including the first time to go to the ground after surgery,the first time to exhaust gas,the length of postoperative hospital stay,the degree of postoperative pain,postoperative complications,including nausea and vomiting,anastomotic fistula,acute intestinal obstruction,abdominal infection,pulmonary infection,and inflammatory factor levels(white blood cell count(WBC)before surgery,1day after surgery,3 day after surgery,and 7 day after surgery)were compared between the two groups.,neutrophil percentage(NEUT%),C-reactive protein(CRP)level).Results: There was no significant difference in general data between the two groups(P>0.05).The time of first descent,first postoperative exhaust time and postoperative hospitalization in ERAS group were shorter than those in abdominal drainage group,and the differences were statistically significant(P<0.05).There was significant difference in postoperative pain degree between the two groups(P<0.05).The incidence of postoperative complications between the two groups was 15.9% and 20.9%,respectively,with no statistical significance(P>0.05).The levels of WBC and NEUT% in ERAS group were lower than those in abdominal drainage group on day 1,day 3 and day 7 after surgery,and the differences between the two groups were statistically significant(P<0.05).CRP level in ERAS group was lower than that in control group on day 1 after surgery,but the difference was not statistically significant,and was significantly lower than that in abdominal drainage group on day 3 and day 7 after surgery,with statistically significant difference(P<0.05).Conclusions:Under the concept of enhanced recovery after surgery,avoiding routine abdominal drainage did not increase the incidence of postoperative complications in elderly patients with gastrointestinal malignancies,and could reduce postoperative pain,reduce the level of inflammatory factors,accelerate the recovery of intestinal function and shorten the length of hospital stay.
